The Lowdown
Alright, grab a coffee and listen up. This is a tough one to write, because honestly, for the next couple of weeks, Kennebunk Beach is playing hard to get. The whole 16-day window is a flat, quiet stretch. We're looking at a serious dry spell.
Let’s get the bad news out of the way first. From now until the end of the month, it’s a ghost town out there. The swell is tiny, mostly under 3ft, and the energy is practically non-existent. For the first week, we are talking about combined swell energy figures stuck in the low double-digits, like 21 or 43 (weak energy). The wind is all over the place, but the waves just aren’t there to make anything of it. There are days with clean, offshore wind, like Monday the 14th and Thursday the 17th, but with a swell height of only 2ft to 3ft and short periods of 7-8 seconds, it's barely a ripple. You'd be floating around more than surfing. It’s the kind of setup that looks more interesting for a kite than a paddle, to be honest.
Then we hit a long, flat gap. From about the 21st through the 27th, the swell stays microscopic. Even when we get a bit of clean offshore breeze, like on Wednesday the 24th with a fresh 35 km/h NNE wind, the swell is only 1ft. You can't make a wave out of nothing. The energy readings are pathetically low, down to 10 or 16 at times.
Now, I said it was tough, but there is one flicker of hope right at the very end. On the morning of Monday, September 28th, we finally get a pulse. The swell picks up to 2ft from the East with a period of 11 seconds (groundswell). The combined energy hits 121 (moderate wave energy). The wind is light and offshore from the NE, promising clean, lined-up conditions. It’s not a monster, but after two weeks of nothing, a clean 2ft wave with some period on it is the absolute standout. The water temp is sitting around 63°, which is about average for the time of year. This is the one to circle on your calendar, but remember, it’s a long way off, so keep your fingers crossed.
Hang in there. It tends not to stay this poor for long.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Kennebunk Beach is 17 km (11 miles) from Biddeford. If you plan a vacation in Maine, look for hotels and other accommodation in Biddeford. Biddeford has rooms for a wide range of budgets as well as car hire and transport links.
